How do I turn on/off automatic verification?

Automatic flossing/verification comes in three flavors, each with its own on/off switch:

These 3 features are not all available for every email service provider integration. If you don't see the switch, that means it isn't available for this particular integration.

To turn them on/off, click the corresponding switch. If it says ON, that means the feature is enabled and active. If it says OFF, that means the feature is disabled and inactive.
